The compounds are white, crystalline solids, readily soluble in organic solvents.

In the specification and claims, the'term lower alkyl designates an alkyl group having from 1, to 2, to 3, to 4 carbon atoms, for example, methyl, ethyl, propyl or butyl; the term lower alkoxy designates an alkoxy group having from 1, to 2, to 3, to 4 carbon atoms, for example, methoxy, ethoxy, propoxy or butoxy; and the term halo designates chloro or bromo.

The compounds are prepared in a 2-step process wherein cis-1-(3-chloro-2-propenyl)-3,5,7-triaza-lazoniatricyclo (3,3,1,1 decane chloride, commercially available as Dowicil 200 antimicrobial, is treated with excess aqueous sodium hydroxide to give the indicated carbinolamine, hereinafter Carbinolamine," according to the following scheme:

e H CH=CHC1 N Excess sodium hydroxide, preferably, 4 molar proportions, is dissolved in water and cooled to room temperature. A quantity of about one mole of Dowicil 200 antimicrobial is added slowly to the caustic solution and the reaction mixture is stirred approximately minutes at ambient temperature. The Carbinolamine which forms is extracted with benzene, the extract is dried over sodium sulfate and the benzene is evaporated to give the Carbinolamine in an approximately 78% yield as a viscous oil.

In the second step, the N-substituted derivatives of 3-carboxamide and 3-thiocarboxamide 7-eis-(3-chloro- 2-propenyl)-1,3,5,7-tetraazabicyclo (3.3.1) nonane, hereinafter referred to as the Compounds or the Compound, are prepared by reacting the Carbinolamine with a lower alkyl, a 5 to 8 carbon atom cycloalkyl, a

phenyl, or a substituted-phenyl, isocyanate or isothiocyanate according to the following scheme:

/CH CH CHC l N NNCHIOH ctr CHCHCl /2 J N bx v t iimmi x Cl-LO fi A 5 clear magnetic resonance.

ca cn=cac1 Prior to making the Compounds, it was expected that the corresponding urethane Compounds would be formed. Unexpectedly, it was found that the Carbinolamine loses one mole of formaldehyde and instead the substituted urea and thiourea Compounds are obtained in good yields. These urea and thiourea Compounds show increased stability and improved antimicrobial activity as compared with Dowicil 200 antimicrobial from which the Carbinolamine is prepared by reaction with aqueous sodium hydroxide.

DESCRIPTION OF THE PREFERRED I EMBODIMENTS The following examples and teachings additionally describe specific embodiments and the best mode contemplated by the inventors of carrying out the invention.

Example A: Preparation of Carbinolamine Intermediate A quantity of g. (2.0 mole) of NaOH was dissolved in 500 ml. water and cooled to room temperature. Grams (0.4 mole) of Dowicil 200 antimicrobial was added slowly to the caustic solution and the reaction mixture stirred ca. 15 minutes at ambient temperature. Extraction with benzene, drying over Na SO, and evaporation of the benzene gave 72 g. (78% yield) of the Carbinolamine, described above, as a viscous oil.

In other procedures, the products can be employed as active constituents in solvent solutions, oil-in-water or water-in-oil emulsions, including cosmetic emulsions. The augmented compositions are adapted to be formulated as concentrates and subsequently diluted with additional liquid or solid adjuvant to produce the ultimate treating compositions. Good results are obtained when employing compositions containing antimicrobial concentrations and usually from about 100 to about 1,000 parts by weight of one or more of the Compounds per million parts of such compositions.

Incorporation of the Compounds of this invention into materials which are subject to bacterial and/or fungal attack inhibits the growth of such microbes and preserves the original value of the materials. The Compounds are sufficiently non-volatile and waterinsoluble that they will persist on or in such materials for long periods of time. Examples of materials which are adversely effected by fungal growth are latex paint films, wood and wooden products. The inventive compounds are sufficiently active against fungi that only small quantities are required to prevent mildew on c i s paint films or wood rot. The compounds are therefore CH CH: CHCl useful for long-term protection against fungal growth in or on materials having a wood basis or a protective. or
